To all whofiz it may concern.-

Be it known that I, GEORGE S. RILEY, a citizen of the United States,residing'at Rochester,in the countyof Monroe and State of New York,haveinvented new and useful Improvements. in, Smoke- Consuming Furnaces, ofwhich the following is a specification.

This inventionhas for its object to provide a new and improvedboiler-furnace of that.

type wherein twin'fireplaces located beneath the boiler are combinedwith valves, dampers, or gates in such manner that as one fireplace ischarged with fresh fuel the smoke and other products of combustion canbe caused to pass, beneath the adjacent fireplace, thereby becomingaerated and'j'rising through the in candescent fuel in transit to thechimney or smoke-stack for the purpose of effectually consuming thesmoke and gases and eeonomizing' in the consumption of fuel.

The invention consists, essentially, in the combination, in asteam-boiler furnace, of twin fireplaces open at their tops and providedat theiradjacentsides with vertical walls, a vertical partitionextending from the boiler down between the said walls to provideopposite longitudinal fines or passage-ways, a pair of adjustablevalves, dampers, or gates arranged, respectively, at or near the loweredge of the partition and below the fireplaces at theadjacent sidesthereof, and a pair of adjustable valves, dampers, or gates arranged influes in the lower portion of the smoke-stack, as will more fullyhereinafter appear.

The invention also consists in other features of construction andcombination or arrangement of parts hereinafter described and claimed,reference being made to the accompanying drawings, in which Figure 1 isa transverse sectional view taken in avertical plane through the twinfireplaces. Fig. 2 is a longitudinal sectional view taken on the line ora, Fig. 1. Fig. 3 is a horizontal sectional view taken on the line y y,Fig. 1;

and Fig. 4 is a vertical sectional view taken on the line 2 2, Fig. 2.

In order to enable those skilled in the art to make and use myinvention, I will now describe the same in detail, referring to thedrawings, wherein- The numeral 1 indicates afurnace structure comprisingfront, rear, and side walls of any materialsuitable for the conditionsrequired and adapted to support a steam-boiler? of any well-known type.The forward portion of the furnace structure is provided with twinfireplaces 3, open at their tops for the unobstructed passage of heat tothe under side of the boiler. The fireplaces comprise grates 4 of anysuitable construction, and the adjacent'sides of the fireplaces areprovided with'vertical walls 5, separatedfrom each other for the passagebetween the same of a vertical partition 6, which extends downward fromthe lower side of the boiler in su'ch'manner as to provide oppositelongitudinal fines or passage-ways 7 and 8, formed, respectively, by thelower end portion of the partition and the vertical side walls of thefireplaces. The vertical partition extends longitudinally from the frontto the rear wall of the furnace structure for the purpose of dividingthe latter into two complete sections, and this partition may be solidor it may be hollow for the passage of air to avoid burning or warping.At or near the lower edge of the partition and beneath the fireplaces atthe adjacent sides thereof is arranged a pairof adjustable valves,dampers, or gates 9 and 10, which are, as here shown, adapted to swingin the arcs of circles 011 rock-shafts l2 and 13, having their forwardends extended through the front Wall of the furnace structure andprovided with suitable handles 14 and 15 or other device for the purposeby which to turn the shafts for adjusting the valves, dampers, or gates.A longitudinal di- Vision-Wall16 divides the base of the furnacestructure into a pair of ash-pits 17 and 18, and this division-wall islocated directly beneath the partition 6 and fiues or passages 7 and 8,so that the free edges of the valves or dampers or gates 9 and 10 can bebrought to rest against the upper end portion of the partition-wall.

A smoke-stack 19 is arranged at one end of the furnace structure and itslower portionor swell contains a vertical partition 20, whichconstitutes a continuation of the longitudinal partition 6 for thepurpose of dividing the lower portion of the smoke-stack into twocorresponding lines 20 and 21. The pair of valves, dampers, or gates 22and 23 are arranged, respectively, in the lines 20 and 21, and at theirouter ends are provided with suitable handles 24 and 25 or other devicesby which to adjust them into the position required. The s1noke-stackistapering at its base portion, and in order to provide the proper squareor other properly-shaped orifices for the arrangement of the valves,dampers,-or gates 22 and 23 I construct the upper portion of thepartition 20 with divergent walls 26 and 27, in which are journaled theinner extremities of the shafts 28 and 29 of the valves, dampers, orgates 22 and 23, which may be square, circular, or other convenientshape. The lower extremities of the divergent walls 26 and 27 are joinedto the partition 20 by converging walls 30and 31, thereby providing theupper nace, of twin fireplaces open at their tops and I provided attheir adjacent sides with vertical walls, a vertical partition extendingfrom the boiler down between the said vertical walls to end portion ofthe partition 20 with a wedgeshaped enlargement for the purpose ofproviding the proper spaces to receive the valves, dampers, or gates,and also affording supports for the shafts which carry such valves,dampers, or gates.

In the drawingsl have exhibited the smoke stack as located at the rearof the furnace structure; but if the boiler is provided withreturn-fines in the usual manner the smokestack will accordingly belocated at the front of the furnace structure in a manner which will beobvious to those skilled in the art, for which reason I do not deem itessential to illustrate this arrangement in the drawings.

In the practical operation of the furnace, if the damper or gate 10 isadjusted to a vertical position and rests against the partition wall 16,and the valve, damper, or gate 23 in the smoke-stack is closed, whilethe damper 9 is horizontal and the damper 22 is open, the smoke andother products of combustion from the fireplace 3 will descend throughthe flue or passage-way 8 to a point beneath the adjacent fireplace andbecoming aerated rise through the incandescent fuel therein, by 1 myhand and affixed my seal in presence of two subscribing witnesses.

which means the smoke and gases from the freshly-charged fireplace areeffectually consumed by passing through the incandescent 5 Obviously if1 flue in the adjacent fireplace.

the damper or gate 9 be vertical, the damper 22 closed, the damper 1Ohorizontal, and the damper 23 open the reverse action will occur. Bythis means as one fireplace is charged with fresh fuel the smoke andother products of combustion therefrom can be caused to pass beneath theadjacent fireplace, there becomin g charged with oxygen, and risethrough the incandescent fuel in transit to the chimney or smoke-stackfor the purpose of effectually consuming the smoke and gases.

My invention provides a simple, economical, and efficient constructionwhich fulfills all the conditions required to consume the smoke in asteam-boiler furnace.

Having thus described my invention, what I claim is- 1. The combination,in a steam-boiler furprovide opposite longitudinal fines or passageways7 and 8, and a pair of adjustable valves,

l dampers, or gates arranged, respectively, be-

low the twin fireplaces at the adjacent sides thereof, substantially asdescribed.

2. The combination, in a steam-boiler furnace, of twin fireplaces openat their tops and provided at their adjacent sides with vertical walls,a vertical partition extending from the boiler down between the saidvertical walls to provide opposite longitudinal fines or passageways, 7and 8, a pair of adjustable valves, dampers, or gates arranged,respectively, be-

a low the fireplaces at the adjacent sides thereof, a smoke-stackcontaining a partition which 1; forms a continuation of the partitionbeneath 3 the boiler for dividing a portion of the smokestack into twofines, and a pair of adjustable valves, dampers, or gates arranged,respect- Iively, in the said fines, substantially as described.

In testimony whereof I have hereunto set GEO. S. RILEY. [L. s]
